Kepler can be used with a set of launchers, each with its way to send and get data from the web server. So io.write() is not a valid way to do this.

I'm not sure about wich launching model and web server you are using, but it seems to be Xavante. 

The correct way to send data to the client on Kepler is to use cgilua.put() and, as in your example, to send content type you should check the corresponding API on
http://www.keplerproject.org/cgilua/reference.html#headers

This allows you to write and use the same Lua script (or Lua Page) in different web servers and launching models.

I hope this has helped and, if you don't mind, we can continue this thread on the Kepler list:
